Spanning Canada and the United States, North America is home to a plethora of major industry players, including Exxon Mobil Corp, the world's second-largest publicly traded company after Royal Dutch Shell. The region's oil and natural gas industry is focused on developing oil sands, deepwater gulf prospects and increasingly profitable shale deposits stretching across the continent. One of the premier sweet spots for deepwater exploration, the Gulf of Mexico is the largest body of water indenting the U.S. continental coastline, and its subsea developments continue to spark both national and international interest.
Geologists apply their knowledge of the earth and its structures to help find and extract oil and gas. Although geologists are usually tied to the location of deposits, they are involved in all aspects of discovery and production. Geologists look at structure and sediment, as well as interpret other geophysical information to help make decisions on where to drill. They must understand the origin, amount and movement of oil as well as any obstacles that may be in the way of deposits before drilling can begin. Geologists will help find deposits all over the world including on land and under the ocean. A strong geoscience background is required for these types of positions.
